The decimetre (British English or decimeter (American English); SI symbol dm) is a unit of length in the metric system, equal to one tenth of a metre, the SI base unit of length. It is equal to ten centimetres and 10 decimetres equal a metre. One decimetre is equivalent to 3.93700787 inches. It can be written in scientific notation as 100×10−3 m (engineering notation) or (exponential notation) — meaning or 0.1 m respectively. The ''c'' is pronounced as /s/, unlike in decametre. The common non-SI metric unit of volume, the litre, is defined as one cubic decimetre (however, from 1901 to 1964, there was a slight difference between the two due to the litre being defined with respect to the kilogram rather than the metre). ==See also== *Metric prefix and deci- *1 E-1 m and Orders of magnitude (length) *Conversion of units, for comparison with other units of length. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Decimetre」の詳細全文を読む スポンサード リンク
